Only one species Bathysiphon eocenicus is recorded <strong>in</strong> all five localities and has a widespread cosmopolitan geographic distribution. 8. It seems that the most of the recorded species are endemic to the tropical-subtropical regions. The existence of a marked differences between the benthic assemblages of the five widespread studied localities which may <strong>in</strong>dicates that they are apparently not so much the results of the different latitudes <strong>in</strong> the tropical and subtropical regions (45º N - 30º S), but rather of variations <strong>in</strong> <strong>foram<strong>in</strong>ifera</strong>l number, planktic/benthic ratio, substrate sediments, depth, water temperature, water-column stability, light penetration, sal<strong>in</strong>ity, nutrients, dissolved oxygen, etc. It seems that the changes <strong>in</strong> paleoceanographic conditions should accentuate the benthic faunal changes. More detailed studies <strong>in</strong> the different localities of these taxa will give a precise answer of this question.
